Abstract

Cette invention concerne un film chauffant caractérisé en ce qu'il comprend : un élément chauffant plan qui présente une paire de bornes ; une paire de fils conducteurs soudés aux bornes ; et deux feuilles de film polyimide thermoplastique qui sont respectivement stratifiées sur les surfaces de l'élément chauffant plan par soudage thermique et qui maintiennent ledit élément chauffant plan dans un état étanche. Dans ledit film chauffant, lesdits films de polyimide thermoplastique peuvent être soudés de manière hermétique par soudage thermique sur l'élément chauffant plan de manière à l'étanchéifier. Cette construction permet d'imperméabiliser le film chauffant suffisamment pour qu'il puisse être utilisé dans l'eau ou dans un endroit exposé à la pluie sans nécessiter de traitement d'imperméabilisation supplémentaire selon les cas et tout en assurant un chauffage efficace.
